nurb boolean problem

[westiemad]

seems an odd way to do it (admittly I'm now a patch modeler), but you could try creating a curve, then selecting it and the surface and doing project curve on surface, then deleting its history and using the trim tool?

darn, I thought it was something in naming it, thats how my instructor showed me, well ill try it anyway, a new tool for me to learn yay!

You have an instructor telling you to make a mouth in a nurbs object with a boolean operation! He must be errr "good" I have never seen a mouth made this way in any tutorials or books I've read. Booleans are generally best to be avoided, are any considerations being made for the flow of the geometry, is the model going to be animated? you might want to look at the book "maya character creation" by Chris Maraffi, the first few chapters cover some of the considerations to be thinking about very well.

Good luck

well the class i took was long ago, and it was on booleans with polygon objects, it was the only way i know how to cut into the geometry of an object

[AndreasMartin]

the only way i know how to cut into the geometry of an objectBooleans are something your realy shouldn't use if you want to achieve a good poly topology.
The problem with booleans comes if you want to smooth your poly object, better cut your poly object with the split polygon tool and build the hole by hand... or bool and connect the vertices that are not connected to the outer poly edges by hand.

For NURBS you don't need booleans, better trim and build the hole by hand.

okay, so I have created the curve and all, selected it and the surface i wanted to project on and did project curve, then the trim tool....What? How do I use that, to me the project curve is nothing more then a more costumizeable (if there is such a word) way to create a unique isoparm but still i cant get the cut I want for the mouth for my dinosaur

[westiemad]

no, now u have a curve laying on the surface of your model, by going to edit nurbs >trim tool, click what u want to keep (look in the help bar down the bottom)

[Tallacus]

you mean two seperate curves

[westiemad]

you might get it projected on the back too, you should be able to delete it.

You could try patch modeling it the normal way, its a bit of a fag, but a nice achievement.

well what I thought is that if i use the subtract boolean with like a nurbs square i would not only cut away the part of the geometry, but i would again geometry that was not originally there that i could use to create for a mouth, its part of my parasauroluphos, and i originally a ep curve and nurbs square and extruding it and going ahead to sculpt it out
